Title: Method for detecting reaction progress by using infrared ray spectroscope
Inventor: SUZUKI TSUNEYUKI
IPC: G01N31/00
Filed: 1979-09-07
Abstract: PURPOSE:To continuously monitor reaction progress by passing part of a reaction liquid continuously through analysis sample distribution type cell and by determining specific atomic group in the reaction liquid. CONSTITUTION:A portion of a reaction liquid is introduced into sample passing  through type cell A installed on the infrared ray spectroscope 3 by means of the  constant volume pump 15 through a withdrawing pipe 14 for a reaction liquid to be  analyzed installed on the reaction vessel 13. Then, it is returned to the reaction vessel 13 through the return pipe 16. The absorption extent of specifc atomic group  in reaction liquid, passing through the cell A at a constant speed, is measured by  the spectroscope 3 on a time basis to monitor the progress of reaction. For instance,  in the case of production of polyester with dibasic acid and ethylene glycol, it is  possible to know the progress of chemical reaction of ester by obtaining acid value  of reaction liquid through measurement of the absorbancy at 2530cm<-1> wavelength  in relation to -COOH group.

Abstract: PURPOSE:To make widths of the lines of a photoresist pattern at an uneven part and at an even part to nearly the same by a method wherein unevenness is formed on the even surface of an insulating film prior to formation of a film for formation of a wiring. CONSTITUTION:Unevenness 7c, 8b are formed on the surfaces of an AsSG film 7 and a polycrystalline silicon film 8 by forming the polycrystalline silicon film 8, and by performing heat treatment. Namely, because unevenness 8b is formed on the flat surface of the part of the polycrystalline silicon film 8 corresponding to an SiO2 film 6, the same unevenness 9b is formed also on the surface of the part corresponding to the SiO2 film 6 of an Al film 9 to be formed on the polycrystalline silicon film 8 thereof at the next process. Consequently when a photoresist 10 is exposed, because an exposing beam is reflected diffusedly even by the unevenness 9b similarly with the unevenness 9a, the amounts of exposure of the photoresist 10 at the part corresponding to the unevenness 9c and the part corresponding to the unevenness 9b are made to nearly the same. Accordingly, widths of the lines of photoresist patterns 10a-10d to be formed according to development become nearly the same.

Title: Optical transmitter-receiver
Inventor: WATABE NOBUTAKA
IPC: H04B10/00
Filed: 1992-05-08
Abstract: PURPOSE:To provide the optical transmitter-receiver having a single optical module. CONSTITUTION:A transmitter 26 receives a transmission data signal to drive a laser diode 22, from which an optical data signal representing the transmission data signal is emitted. The laser diode 22 emits a backward optical leakage signal simultaneously. A photodiode 23 detects the backward optical leakage signal as an optical monitor signal and outputs an electric monitor signal. A transmitter 26 receives the electric monitor signal to control output power of the laser diode 22 to be a stable level. When the transmitter 26 receives no transmission data signal, the laser diode 22 acts like an optical amplifier for an incident optical data signal and sends the amplified optical data signal to the photodiode 23. The photodiode 23 converts the amplified optical data signal into the electric reception signal. A receiver 24 receives the electric reception signal and discriminates it and outputs the received data signal representing the incident optical data signal.

Abstract: PURPOSE: To prevent the leak of current from a short-circuited row to a bit line by repeatedly impressing a precondition pulse to the short-circuited memory cell until the threshold voltage of that shortcircuited memory cell gets higher as a result of comparison with a regular precondition level. CONSTITUTION: Under the control of a following state controller 34, the conditioning pulse is impressed to the mutually short-circuited cells of a memory array 36, a public threshold voltage A is impressed to that gate, and one of cells is read. At the same time, a voltage B lower than the voltage A is impressed to the gate of shortcircuited reference cell, the short-circuited reference cell is read and during that reading, the threshold voltage of one of two shortcircuited cells is compared with the threshold voltage of the shortcircuited reference cell. The short-circuited reference cell has the threshold voltage lower than a usually required level but enough for blocking the excessive erasure of short-circuited cells and its comparison is performed by a sense amplifier 78.  Besides, the reference cell of different threshold voltage is selected and coupled to the amplifier 78 by a reference cell selector circuit 35. Thus, the leak of current from the short-circuited row to the bit line is prevented.
